128 equals x to the power 7 what is x how do i use logarithms to solve it?
128 = x7 (we see that x > 0, since x is raised to an odd power) 27 = x7 (this is true only when x = 2) 2 = x Remember that a logarithm is an exponent. The statement 128 = x7 is equivalent to logx 128 = 7. logx 128 = 7 log 128/log x = 7 (or reverse the both sides) log x/log 128 = 1/7 (multiply by log 128 to both sides) log x = log128/7 (or use base 10 for the logarithm) log10 x = log128/7 (write the equivalent statement) 10log 128/7 = x 2 = x or use the natural log, ln. 128 = x7 ln 128 = ln x7 ln 128 = 7ln x (ln 128)/7 = ln x e(ln128)/7 = elnx (elnx = x ) 2 = x
How does f(x)7x change over the interval from x5 to x7?
If the x value changes u, then the y value changes by 7u.
What is 23 is what percent of 46?
46 is the 23% of 200.23 x = 4623 x = 4600x = 200
X2 - 4x - 29 equals -10?
Assuming that by expressing that equation as a question you're looking to solve for x: x2 - 4x - 29 = -10 x2 - 4x + 4 = 23 (x - 2)2 = 23 x - 2 = ± √23 x = 2 ± √23

How do you simplify the square root of x to the seventh power?
sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5
X7-4 plus x7 plus 4?
Depends on where the parentheses are. X(7-4) + X7 + 4 = 10X + 4 X(7-4) + X(7+4) = 14X
What is x to the power of 8 divided by x?
x7
What is the answer x to power of 4 multiplied by x to power of 10 divided by x to power of 7?
(x4 * x10)/(x7)x14/x714 - 7 = 7= x7===
Is x7 the same as 7x?
In mathematics, the expression x7 typically represents the product of x and 7, while 7x represents the product of 7 and x. In general, the order of terms in a multiplication expression does not change the result. However, in algebra, the order of terms can be important when simplifying or solving equations.
What does x7 mean?
In mathematics, the symbol "x" typically represents multiplication. Therefore, "x7" means multiplying a number by 7. For example, if you have the expression 5 x 7, it would equal 35.
What is the unit rate in x x7?
It is 1 in 7.
How do you factor x to the fourteenth power minus 49?
There is a formula for the "difference of squares." In this case, the answer is (x7 - 7)(x7 + 7)
What x7 gives you 28?
To find what x multiplied by 7 equals 28, you can set up the equation 7x = 28. To solve for x, divide both sides by 7: x = 28 / 7. Simplifying, x = 4. Therefore, 4 multiplied by 7 equals 28.
